摘　　要：文章描述了一个新型的光纤振动传感器用于电机的健康监测,频率范围在20-100Hz,它有技术先进和成本低廉两个突出的特点,是机械振动检测的最优化设计。Vibration monitoring in high power electric machines, such as generators and transformers, presents some difficulties due to the insulation and EM immunity requirements. However, the negative influence of the electromagnetic interference（EMI） can be a real problem when electrical signals are used to detect and transmit physical parameters in noisy environments such as electric power generator plants with high levels of EMI. Such problems can be solved by using optical fiber sensors, which allow field measurements and remote control without electrical wires. The present paper describes a novel fiber optic vibration sensor for health monitoring of electrical machines with vibration frequency of 20-100 Hz., and it is the optimized design for mechanical vibration with relatively simple technologies and moderate costs.
